1. Scarsa dissipazione del calore interno dei tablet PC industriali
Industrial tablet computers are in a harsh environment, in addition to high temperature, there is also a lot of dust. When dust enters the industrial tablet computer, the heat dissipation effect of various boards, CPUs and other electronic components is poor, causing the industrial tablet computer to "crash".
2. Pulisci frequentemente i file temporanei
Quando il tablet PC industriale è in esecuzione, genererà un numero elevato di file temporanei. Questi file occupano il disco rigido e le risorse di sistema e influiscono sulla velocità del tablet PC industriale per elaborare le informazioni.
Controllare regolarmente il disco rigido ed eliminare i file temporanei per migliorare la velocità di elaborazione del tablet PC industriale.
3. La quantità di dati è eccessiva e l'efficienza della CPU è bassa
When the industrial panel computer processes too many field signals transmitted by the PLC, the CPU efficiency of the industrial panel computer is low, and the memory is small, and it cannot recognize and process so many signals at the same time. These signals "crash" and cause the industrial panel computer to "crash". ".
Due to the limitation of the memory slot of the industrial panel computer motherboard, the memory is intelligently expanded to 64M. The main solution is to reduce the frequency of processing and identifying on-site signals by industrial tablet computers to avoid signal "car crashes".
The specific plan is: when the industrial panel computer is connected to the field signal through the PLC, the signal sampling period is set to be more than 2s, and the analog signal with little change, such as temperature, can be set to more than 10s. In the process of programming, after setting the sampling period of all analog signals to more than 2s, the phenomenon of industrial panel computer "crash" rarely occurs.
4. Controllare la ventola della CPU e la ventola dell'alimentatore host
The heat dissipation of industrial tablet computers is mainly carried out by CPU fans and power supply fans. When the CPU fan is damaged, the temperature of the CPU rises, which can easily cause the industrial panel computer to "crash".
Controllare frequentemente la ventola del computer del pannello industriale e sostituire la ventola danneggiata in tempo. Quando il computer del pannello industriale nella sala di controllo centrale lascia la fabbrica, nella CPU viene installato solo un dissipatore di calore, senza ventola, e successivamente viene installata una speciale ventola di raffreddamento e la temperatura della CPU viene ridotta di quasi 5 gradi .
The above are the possible reasons for the crash of industrial tablet computers. In general, in addition to correct operation, necessary maintenance is also required. Pay attention to the temperature during use, and often clean up temporary files. Pay attention to these matters. It can reduce the occurrence of "crash" of industrial tablet computers.
There are two main related reasons for the "crash" of daily industrial tablet computers. Board failures and system failures are the most basic and core parts of hardware and software, and their applications are crucial. So this requires us to follow the precautions and repair and maintain in time when we usually apply.
